Ultra-compressed communication mode. Cuts token usage 20-50% (75% upper bound) by dropping filler, articles, pleasantries, and hedging while keeping full technical accuracy. Derived from Matt Pocock's MIT-licensed caveman with: (1) 3 stdlib Python tools (deterministic compressor, token-savings estimator with $/Mtok cost extrapolation, lint that detects banned vocab with code-block + exception-zone whitelisting), (2) 3 references citing 7-8 sources (compression principles, when caveman backfires, companion tooling), (3) cs-caveman-mode persona agent + /cs-caveman slash command. Matt's persistence rules + auto-clarity exception preserved verbatim per MIT.

Skill for legal research on Italian and EU sources: legislation, administrative practice, and case law. Encode a working method, not an opinion: routing to official sources, citations with verifiable references, validity checks including ratione temporis, query minimization for contexts covered by professional secrecy, and concise output by default. The Agent Skills format is an open standard: the skill was created for Claude (claude.ai, Desktop, Cowork, Claude Code) and is reusable in tools that adopt the same format.
